Error
Recommended action(s)
Configuration lost
The meter configuration has reset to default values and the
meter is not configured correctly to measure flow and the
meter has performed a Cold Start.
•
Unless the Cold Start occurred after upgrading firmware,
replace the CPU Module (see
).
•
If the cold start occurred after a firmware upgrade, fully re-
configure the meter from a previously saved configuration
using the
Tools
→
Edit/Compare Configuration
in
MeterLink.
Electronics Temperature is Out
Of Nominal Range
Temperature of the electronics is out of nominal operating
range (below -40 °C or above 100 °C) which could lead to a
system failure.
•
Attempt to warm or cool the meter electronics housing.
•
If the electronics is mounted to the meter and the process
fluid in the meter is over 65 °C, you must remote mount the
electronics off of the meter body.
•
Collect a Maintenance log using MeterLink while the meter
is experiencing the issue and contact your Emerson Flow
service representative.
Flow pressure is outside the
alarm limits
•
Startup Issues:
—
Verify that there is voltage to the pressure sensor from
either the meter's power supply board or from an
external power supply.
—
If using an analog pressure device, verify that the
pressure sensor is properly wired to the connector.
—
Verify the input is properly configured for your pressure
input.
—
If using a flow computer to write pressure to the meter,
verify that it is properly writing to fixed flow pressure in
the proper units.
•
Run Time Issues:
—
If using an analog pressure device and input reading is 0,
check if
IsAI2Avail
is equal to 1 in the Meter Information
dialog in MeterLink. If it is not 1, either the I/O Board has
been removed or is damaged. Reinstall or replace the
CPU Module if this value is 0.
—
If using an analog pressure device, verify that the
pressure sensor is working properly.
—
If using an analog pressure device, recheck wiring and
switch settings.
—
If a flow computer is writing values to the fixed flow
pressure, verify that the flow computer is still writing
valid values without Modbus write errors.
—
Re-verify the pressure input settings are correct.
